Tree rings
I think everyone knows that trees lay one growth ring per year, and by counting them from the pith to the bark we can find out the tree's age.
Ring thickness and space can vary as well, but how can we count the rings to species that rings are not so well visible at the exposed end? Do we need actually a microscope?
Below its a photo of one of my olive trees exposed end. Any ideas how to count the rings? or Is there any chance somebody can tell me the age of this tree?

Re: Tree rings
You need to cut a slice, clean it and then use a strong magnifying glass and lots of patience to count the rings.
Taking into consideration that the trees we dig are collected from arid areas, with harsh climate (windy, non-fertile soil), sometimes with sheep/goats grazing on all new vegetation, the rings must be very very thin and difficult to see, even under magnification.

Re: Tree rings
Hello Greg. I would say from the picture you have an extremely venerable tree there. I would cut off a slice and spend some time polishing it to a very high finish. A very powerful magnifying glass with its own stand and a very sharp pencil to mark and count is useful. I have removed branches from our wet shores and counted a couple of hundred rings in 5 cm. I'm sure you can beat that easily.

Re: Tree rings
Will and Stauros , thanks for the advice.
I think I will use a magnifying glass in combination with a camera. I will take a photo and then try to count the rings on my pc.
